GLUING-MACHINE FOR STENCIL-FRAMES.

Specification of Letters Patent.

Patented Jan. 12, 191i 7.

Application filed January 15, 1916. Serial No. 7 2,343.

To all whom it may concern:

Be it known that I, STERLING ELLIOTT,

a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Gluing-Machines for Stenoil-Frames, of which the following is a specification.

This invention relates to machines for sizing the frames of stencil-blanks, and is particularly adapted for the sizing of the edge frames, and supporting pieces of the stencils 0r address-plates of the type disclosed in my Patent #1,068,578. One of the principal objects of the invention is to provide a machine by which the stencil-frames are fed from a supplyholder into a gluing-tank and are then conveyed from the gluing-tank to conveyingmeans, whereon they are allowed to dry and by which they are delivered to stackingmeans by which they are stacked in edge Wise position in a suitable horizontal receiver.

Another important object of the invention is to provide two independent but complemental belts for conveying the stencilframes from the gluing-tank to the stacking-means, the two belts being so arranged that one face of the stencil-frame is exposed to the atmosphere while on one belt, and the other face exposed to the atmosphere while on the other belt, the blanks being turned over in passing from the one belt to the other.

Another object is the provision at the entrance to the gluing-tank of a pair of accelerating rolls which are adapted to draw each stencil-frame engaged by it away from the following stencil-frames, so that each stencil-frame will, as it enters the gluingtank, be momentarily spaced from the other frames, thus to assist in feeding the stencil-frames along and to prevent said frames from crowding or overlapping, and thereby becoming wedged in the guide-way along which-they are moved.

A further object is to provide an ejecting means by which movement of each stencilframe, as it is drawn from the gluing tank, is accelerated, and thereby quickly drawn away from the following stencil-frames so that the frames will not be congested or crowded in the track at such points, and thereby injured.

A further object is to provide for moving the conveying means for the stencil-.

frames faster than the speed of delivery of the stencil-frames thereto, so that the stencil-frames will be sufficiently spaced from each other upon the conveying-means to admit of thorough drying of the edges of the frame.

A further object is the provision of means to facilitate the removal of the stencilframes from the bottom of the pile without injury thereto, or to an adjacent frame, each means operating to move the frames in a curvilinear direction while removing them from the bottom of the pile thereby to turn then in a horizontal plane with respect to the frames above them.

Figure 1 is a side elevation of one endportion of a sizing-machine for stencilframes embodying this invention. Fig. 2 is a side elevation of the middle portion of said machine. Fig. 3 is a longitudinal vertical section of the other end-portion of said machine. Fig. 4 is a horizontal section of the machine shown in Fig. 1, taken on the dotted line 414. Fig. 5 is an enlarged detail view of the track along which the stenoil-frames or blanks are fed from the holder through the gluing-tank and to the conveying-means. Fig. 6 is an enlarged top plan view of the feeding-mechanism .by which the blanks are fed through the track, the ejector arm being shown in retracted position. Fig. 7 is a top plan view of a portion of the feeding-mechanism, with the ejector arm in projected position. Fig. 8 is a detail section taken longitudinally through the exit end of the gluing-tank. Fig. 9 is a top plan view of the stacking apparatus, and receiver. Fig. 10 is a section on the line 10--1O of Fig. 9. Fig. 11 is a section on the line 1111 of Fig. 9. Fig. 12 is a-section on the line 1212 of Fig. 9. Fig. 13 is a section on the line 1313 of Fig. 9.

As here shown the frame 10, supports the glue-tank 11. Said frame 10 may be of any suitable construction and has parallel transverse beams or bars 14 upon which the terminals of a rectangular reinforcing frame 15 of the tank 11 are supported. The tank 11 is preferably of sheet metal and has a curved bottom wall 16. and parallel segmental side walls 17. The upper edges of the side walls ahd bottom Wall are turned over the frame 15, as at 18, Fig. 8, to secure the tank in said frame. Thus the tank may be removed from its supporting-frame 10,

by lifting the frame 15 from these supports A pump the tank.

14, for cleaning or other purposes. 19 is provided in connection with This tank is adapted to contain glue, lac, or any other equivalent cementitious substance, which is to be employed in sizing the stencil-frames, and is herein referred to as a gluing tank.

The supply of stencil-frames which are to be glued, are arranged in a pile in a suitable holder herein shown as comprising a base-plate 20, vertical channel-shaped guiding-members 21 mounted thereon, and a vertical plate or bar 22, see Figs. 1 and 5. The stencil-frames are fed from this holder by feeding-mechanism ;-which successively removes them from the bottom of the pile.

- The feeding-mechanism here shown is of novel construction, and comprises an e ector arm 25, secured to the upper end of a shaft 26, and arranged for oscillation in a horizontal plane, over the upper face of a table 27 and across the bottom face of the base plate 20, which is mounted on said table (see Fig. 5).

An arcuate guide-passage 28 (see Figs. 6 and 7 is formed in the upper face of the table 27, which extends beneath the opening in the base-plate 20, through which the stencil-frames pass, said passage being thus adapted to receive the lowermost stencilframe of the pile. The ejector arm has its free end-portion 29, arranged tomove lengthwise of said passage 28, and'said endportion is formed with a tongue 30, which is extended forward, and also offset downwardly with respect to the arm, thereby to form an abrupt shoulder or engaging-portion at the junction of the tongue and arm. The guide-passage 28 has an arcuate groove in its bottom, shaped to correspond with and permit unobstructed movement of said tongue 30. As shown in'Figs. 4 to 6, the ejector arm has a backward throw suflicient to enable itscshoulder to pass the opening in the base-plate, so that the lowermost stencilframe will rest on the tongue, and has a forward throw sufficient for its shoulder to engage the rear edge of said lowermost stencil-frame and move said frame forward a distance sufficient to cause its front end to be engaged by a pair of feeding-rolls. Thus as the ejector arm is oscillated the stencilframes are successively removed from the bottom of the pile. By reason of the guidepassage being arcuate and the ejector arm arranged to oscillate on an axis coincident with the center of the arc of said passage, and the holder for the stencil-frames being arranged in a plane substantiall tangential to said arc, the lowermost stenci -frame will be removed from the bottom of the pile in a curvilinear direction corresponding to said are, instead of being moved straight-away,

with the result that it is turned in a horishelzontal plane while it is being so moved and there is less liability of the inner edges of the stencil-frames engaging each other, and thus obstructing sliding movement of the lowermost-frame.

The shaft 26is turned to oscillate the ejector arm by means of a shaft 33, having a terminal gear 34 driven from'a pinion 35,

on a stub shaft 36, which is directly con-' nected to the motor or other power source through a belt 37 and belt pulley 38. The shaft 33 extends transversely and is journalled in parallel longitudinal supporting bars 39, which are suitably connected to the vertical bars 40 of a frame which supports the feeding-mechanism, see Fig. 1. To oscillate the shaft 26, a pair of meshing bevel pinions 42, 43, a crank 44, and a pitman 45 are employed. Pinion 42 is secured to shaft 33, and pitman 45 is eccen'trically connected to a disk upon the upper face of pinion 43. The crank 44. is secured to the. shaft 26.

The pitman 45and crank 44 are adjustably 7 connected so that the throw of the ejector arm may be adjusted.

The rotation of shaft 33 will be communicated to shaft 26 through the pitman 45 to oscillate the ejector arm 25, and thereby eflect an intermittent discharge of the stenpair of longitudinally curved bars connected y transverse braces 23, the upper ends of which bars are secured to the top of the table 27 see Fig. 5, and the remaining portions being secured to the frame at several points, whereby they are held in fixed relation. This track extends downward into and out of the tank, a portion thereof being arranged below the level of the glue contained in the tank and is employed to support and guide the stencil-frames while they are being moved along from the holder into and out of the tank, the frames being submerged while in transit. The inner or adjacent edges of said bars are grooved longitudinally, see Fig. 4, and said grooves are arranged in continuation of the guide-passage in the table, so that the stencil-frames, upon leaving said guide-passage, will enter the grooved edges of the curved bars and will be supported and guided by them.

As the stencil-frames pass to the track they are engaged by a pair of feeding rolls 46, 47, see Fig. 5, an thereby positively movedalong the grooves of the track, each frame abutting against the frame ahead of it. These feeding-rolls are arranged at right angles tothe curved bars form ng the track,and therefore, first engage a corner mai ens and as said positively moved stencil-frame engages the grooves in the bars, and the bars are spaced apart a distance approximately equal to the width of a stencil-frame, said stencil-frame will be turned to a position in parallel relation with the track. The walls or" the grooves of the bars forming the track being longitudinally curved, ofi'erfa certain resistance to the fiatstencil-frames, and consequently while the stencil-frames may be moved along the track by the feeding rolls 46 and &7, each frame engaging the frame ahead of it, they will not fall by gravity. As here shown the rolls 4:6 and 4:7 each comprise (see Fig. 6) disks which are secured to shafts 50 and 51, and maintained in spaced relation by hubs or collars 52. Herein the shafts 50, 51, are connected b meshing pinions 53, 54, and are driven y a chain 55., which passes over sprocket-wheels 56 and 57 arranged respectively on shafts 50 and 33.

While passing along the track the stencilframes abut together and as the track is very long and is curved longitudinally there is danger of the frames overlapping and becoming wedged in the grooves of the track, and to obviate this tendency another pair of feeding-rolls 58, 59, is employed, which rolls are herein located some distance in advance of the feeding-rolls 46, 47, being here shown as located just before the track enters the tank, and said additional feedingrolls serve to engage the stencil frames presented to them, and to independently feed them along the track. The rolls 58 and 59 are here shown as of greater diameter than the rolls 46 and 47, and are, or may be, driven at the same rate of speed, so that the rate of speed of each stencil-frame which they engage is, therefore, suddenly increased,

and thereby moved away from the following stencil-frames, but into abutting relation with the frames ahead of it. Herein the rolls 58 and 59 are solid and are mounted upon shafts 60 and 61, journaled in the bars 39, and connected at one end by meshing pinions 62, 63. The shaft 61 has a sprocket-wheel 64, and is driven by a chain 65, which passes over said sprocket-wheel and over a sprocket-wheel 66 on shaft 50.

As the stencil-frames emerge from the track at the exit end of the tank they are engaged by the accelerating and ejecting rolls 67 and 68, which rolls also serve to squeeze the frames and remove the surplus glue. The roll 67 is mounted on shaft 33, and the roll 68 is mounted'on a parallel shaft 69, said shafts being connected bythey are ejected from the tank are thrown upon suitable conveying-means, in spaced relation to each other, so'that they may be thoroughly exposed for drying while en route to the stacking apparatus. A deflecting arm 73 is supported by a transverse bar 74, above the conveying-means, in position to deflect the stencil-frames onto said means, as they are ejected from the track by the rolls 67 and 68, see Fig. 4.

The conveying-means here shown comprises a belt 72, acting in conjunction with a belt 7 5, to convey the stencibframcs from the gluing-tank to the stacking-apparatus. As shown in Figs. 1, 3, and 8, the belts 72 and 7 5 are arranged in troughs comprisingparallel side walls 76, and a door board 77 connecting the same. Rolls 78 are provided for each belt at the end of the trough, and a tensioning-means is provided for the belt 72, adjacent the gluingapparatus. This tensioning-means, see Fig, 1, comprises a roll 79, journaled between the free end of pivoted arms 80, having a minute. Weight 81. The belt 72 passes around this terminal roll 78, about the tension-roll 7t, and then successively over drivingmolls 82, 83, 84, and 85, respectively mounted on shafts 86, 87, 88 and 89, journaled in parallel plates 189. The rotation of shaft 89, which is connected to the motor or other power source by a chain 90, as will be hereinafter described, translated to the shaft 88 through a pinion 91 to the shaft 87, by a pinion 92, which meshes with pinion 91; and to the shaft 86, by a inion 93, which meshes with pinion 92. he belts 72 and 75 are driven at a faster speed than the speed of delivery of the stencil-frame thereto, so that the stencilframes will be more or less widely spaced apart thereon, thus admitting of the edges being exposed to enable them to quickly dry.

Referring jointly now to Figs. 1, 2, and illustrating the completed machine: Afterthe glued stencil-frames are passed onto the belt 72 by the ejecting-rolls 67 and 68, they are carried along to the end of the belt, and there dropped ontothe belt 75, see Fig. 3. The belt 72 is of considerable length so that the upper faces of the stencil-frames are, in

their passage along the said belt, exposed for a period of time suflicient to thoroughly dry them. A curved chute 95, leadsfrom the end ofthe belt 72, down onto the upper portion of the belt 75, see Fig. 3, and this chute serves to turn the stencil-frames over so that the face of. the stencil-frame which was formerly in engagement with the belt 72 is uppermost when it falls upon belt 75, and is exposed to the atmosphere for drying.

'Belt 75 is also of sufficient length to insure the drying of the exposed face of the stenoil-frame, before it enters the stacking-apparatus to which the belt 75 leads. The belts are or may be intermediately supported by transverse rolls 96, and the vertical bars 97 are or may be employed in maintaining." the side walls 76 of the two belt-troughs in the n-opcr spaced relation. One terminal roll 48' of the belt 7 is j ournaled, see Fig. 2, upon a shaft 97 having a terminal sprocketwheel 98, over which the chain 90 previously referred to operates. After passing about the rolls 78 the belt passes successively over driving-rolls 98, 99, 100', an idler" roll 101, about a tcnsioning-roll 102, and over a second idler 103, back over the transverse rolls 96. The rolls 98, 99, 100, are driven from the main drive-shaft 104, through the belt 105, which passes about a belt-wheel 106, secured to a stub-shaft 107, said shaft 107 connecting, by a smaller pinion 108, with the shaft 109 through the pinion 110 thereof. A pinion 111 on the other end of shaft 109, see Fig. 9, meshes with apinion 112 on shaft 97, to thereb-y'drive the roll 78 and the sprocket-wheel 98. The pinion 111 also meshes with a pinion 113 on shaft 114 of roll 99, thereby driving said roll, and

the shaft 115 of roll 100 is driven through. its pinion 116 which meshes with pinion 113.

The tensioning-i OH 102 is journaled between the free ends of pivoted arms 117, having a weight 118 whereby the belt is maintained taut. The shafts 97, 109, 114, and 115 are terminally journaled in parallel supporting- .plates 119, which are mounted on the supporting-frame 120 and spaced above the top thereof, by suitable legs 121.

It will now be seen that the machine, as thus far described, makes provision for feeding the stencil-frames from a supply-holder along a track and into and out of a gluingtank; and for ejecting the stencil-frames from said tank at an accelerated speed to deliver them upon the first conveyor-belt 72; that one surface of each stencil-frame is allowed to dry while in transit on the upper c0nveyer-belt 72; that the stencil-frame is then turned over as it falls upon the lower conveyer-belt 7 5; so that its other face will be exposed and allowed to dry before it- This passes into the stacking apparatus.

stacking apparatus comprlses essentially a 4 vertical chute 122; a horizontal chute 123, see Fig. 11, and a receiving trough 124, which is horizontally disposed and arranged at right-angles to the chute 123. The vertical chute 122, opens at its lower end into the horizontal chute 123, and the bottom of said chute 123 comprises the upper portion of a horizontal belt 126, arranged for movement over a supporting board 127. Terminal-rolls 128 and 129, the latter of which is driven by ameans to be later described, are provided for said belt, 126, and this belt is moved at a rate of speed suflicient to tilt or turn the stencil-frames, as they emerge fromthe vertical chute 122, and dispose them with their longer edges horizontally arranged.

The side-walls 130 of the chute 123, see, i

135, which are secured to shafts 136, 137,

arranged at right angles to the chute 123, and in line with the longitudinal center of the receiving-trough 124, see Figs. 9, 11. These worms act to move the stencil-frames forwardly into the receiving-trough, The terminals of the worm-shafts 136 and 137 are connected by meshing pinions 138 and 139, and the shaft 136 is herein driven from the transverse-shaft 114 by engaging bevelpinions 141, 142. It will' be remembered that shaft 114 carries the roll 99, and is driven from the main power source by the belt 105. It is desired that each stencilframe, as it passes from the chute 123 into the receiving-trough 124, be accelerated so that it will be widely separated from the following stencil-frames, and the worms given suflicient time to move each stencilframe out of the path of the next succeeding stencil-frame. For this purpose, there are provided accelerating rolls 145 and 146, mounted on the upper end of vertical stubshafts 147, 148, located on opposite sides of the belt 126, see Figs. 11 and 13. The rolls 145 and 146 engage the lower edge of the stencil-frames and being positively driven at a rate of speed greater than the belt 126, they positively feed and also accelerate the movement of the stencil-frames and draw them away from the next succeeding stencil-frame, and positively project into position for engagement by the worm. To prevent clogging of the-stencil-frames between the worms, I provide an arrestingdevice which is periodically operated to retain and liberate at the proper time the foremost stencil-frame in the chute 123, to hold it against further movement therethrough, until the worm-shafts have made a complete rotation, which is suflicient to pass any stencil-frame out of the path of the next succeeding stencil-frame. This arresting-device, see Figs. 9 and 12, comprises an Lshaped arm 149, pivoted in a bracket 150, and having a hook 151, which passes through a slot 152, in the sidewall 130, and into the path of that stencil-frame next to the stencil-frame which has just been en gaged by the accelerating rolls 145 and 146. The hook 151 is normally held in arresting position by a contractile spring 153, but is periodically swung into inoperative position, to allow another stencil to be moved forward into engagement with the rolls 145 and 146, by a pitman 154, having an eccentric conneotion 155 with the worm shaft 136. Upon each' rotation of the worm-shaft the pitman is moved outwardly to swing the arm 149,

against the opposition of spring 153, to therefore Withdraw therhook 151 from the path of the stencil-frames in the chute 1-23. The belt 126 is driven from a pinion 139' of a worm shaft 137, see Fig. 12, through multiplying gears 156'and 157, the latter being secured to the shaft of roll 129.

To relieve the strain on the worm-wheels and to assist them in moving the stencilframes through the trough 124,- there is pro- Vided a belt 159, arranged for movement over transverse rolls 160 and 161, and suitably tensioned by an idler roll 162, see Fig. 10. The upper portion of this belt operates in a longitudinal opening 163, formed in the bottom of receiving trough 124, and is arranged to receive the stencil-frames after they have been projected a short distance into the trough by the worms. This belt is driven from the shaft 114 by means of a belt 164, passing around the belt-wheels 165, 166, gears 167, 168, on the shafts 169, 170, and gears 171, 172, respectively, secured to shafts l69=and the shafts 173 of roll 161. The stencil-frames pass off of the belt 159 onto a pivoted bar 175, see Figs. '10 and 13. This bar has a rectangular extension 176, which may be employed as a hand-grip for tilting the member 175, when a number of stencil-frames, sufficient to fill a box have been deposited thereon. The shaft 148 isextended below the support 148 of the chute 123, and has at its lower end a belt wheel 180. A belt 181 connects the wheel 180 and a belt wheel 182 on shaft 114 and the rolls 145, 146 are thus driven from the shaft 114.
